The LX256V-35FN484C is a digital chip designed for special purpose analog switches. It is designed to provide an increased number of switch instances within a single chip, allowing for dense, space-saving designs. This chip provides complex, flexible and programmable control of digital and analog signals, enabling it to support a diverse range of applications. It is particularly suitable for switching medium-power signals such as those used in communications, embedded control, DAC and ADC switching.The device has two physical inputs and four control pins that can be configured in a variety of combinations. Each switch is enabled by either a high or low logic level, and the outputs can follow the logic level of the inputs when in the disabled state. In the active state, the output logic level is determined by an on-chip logic circuit. The device also provides a power-on reset circuit, allowing the state of the switches to be determined immediately after powering up the device.

The control pins of the LX256V-35FN484C are programmable, allowing users to select various combinations of functionality by configuring the control pins in different states. These combinations include the following: active low reset (enabling the device on a high logic level); inactive high reset (inverting the logic level to disable the device); and active low set/clear (enabling the device on a high logic level for a set/clear pulse, followed by a low logic level to disable the device).

The LX256V-35FN484C can be used in a variety of applications, including in communications systems, where it can be used to switch between multiple audio-frequency signals and data paths. It can also be used in SSI and SPI bus logic level conversion applications, providing bidirectional logic-level conversion between medium-power and low-voltage logic interfaces. In addition, the device can be used to provide a logic level conversion between TTL, CMOS, and LVDS/LVPECL interfaces without the need for external voltage sources. It also supports inter-IC communications in multi-chip systems, enabling the communication of control signals between two ICs. The device is also suitable for medium-power switching applications, such as in medical device, automotive and other high-reliability markets, where the device can be used to switch various analog signals.

The LX256V-35FN484C provides an integrated power-on reset circuit, allowing the device to be reset on power-up to ensure that it is always initialized to a known state. The device also provides an over-temperature protection circuit, as well as current sensing and overload protection features to prevent the device from being damaged in the event of a fault. The device also has a built-in ESD protection circuit, allowing it to withstand electrostatic discharge and other external surges. The device’s low-power design and wide voltage and temperature ranges make it suitable for a range of embedded and industrial applications.

In summary, the LX256V-35FN484C is an advanced digital chip designed for special purpose analog switches. It provides an increased number of switch instances within a single chip, while allowing complex, flexible and programmable control of digital and analog signals. The device is suitable for a range of applications, including communications systems, bidirectional logic-level conversions, and medium-power switching. It also features an integrated power-on reset circuit, over-temperature protection, current sensing and overload protection, and built-in ESD protection, making it suitable for a range of embedded and industrial applications.
